How to change the direction of a beam from horizontal to vertical.
- 11 Apr 2017
The useful parts
You can use the L-shaped beams, they come in bigger and smaller variety.
You could use the double angular beam which we usually use to connect our motors.
You could use the T-shaped black beam.
Use two pins again
For some of the angular beams you should use the axle pin, the one that combines an axle part and a pin part.
The beams that have cross openings are the small L-shaped beam and the double angular beam.
Sometimes you need to extend the construction but not only horizontally but also vertically. And in this video we'll stop at some of the parts and the principles for extending the construction vertically. As an example we'll use this touch sensor. And the goal is to place this touch sensor at the front of the robot but pointing vertically up. What I'll do is take a beam, 2 pins and as you might remember from the previous video from the course we don't add the pins next to each other. We leave at least one hole between them and we have the 2 pins with the beam pointing forward. Our goal is to have the touch sensor in this position. So, we must change the direction. You can see that the direction of this whole construction - the beam is horizontal, now we must change it to vertical. And we can use a number of different parts. We have these L-shaped beams. This one is 3x5 and this one is 2x4 holes. We have the double angular beam and we can all use them to change the direction. How could we do this? First, I'll take the L-shaped beam, add 2 black pins, place here and now using the long blue pin we can attach the sensor.
Like this. And as a result we've changed the direction of our construction. Our sensor is pointing up. We can also use other parts. For example, we can use this double angular white beam and it will serve again the same purpose. The only difference is that here we should place an axle pin, a blue axle pin and one black pin,
attach and in the same way attach the touch sensor.
Like this. We can stack these solutions and we can now change the direction. We can change the direction again to horizontal using this L-shaped beam but this one is 2x4. I'll use a blue pin - long blue pin and one of the black pins. Now, because this is 2x4 and here we have only 2 holes what happens is that there isn't a whole in between these 2 holes to leave space so we are kind of like bound by the construction by the decision of the maker of these Lego parts to have these 2 pins next to each other. Then we add them right here and one more long blue pin and we add the sensor. And now we have a horizontal construction, a vertical construction and then a horizontal again. And we've changed the direction twice - first vertically and then horizontally.
